KEY-BASE FOR PIlASTIC I MATERIAL. H E I E D Specification of Letters Patent. Patenteh Sept, 13, 1921 Application filed September 21, 1918. Serial No. 255,197.

To all whom it may concern:

Be it known that I, JONATHAN O. FOWLER, a cltizen of the United States of America,

and a resident of New York, in the county and State of New York, have invented a certain new and useful Key-Base for Plastic Material, of which the following is a specification, the same being a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it This invention relates to wall structures and comprises a device having a foundation of fabric and a superposed reinforcing and plaster retaining metal material such as a woven wire work or metal strands.

' The object ofthe invention is to provide a covering or key base to be used for walls of buildings to which cement, concrete or other plastic material may be directly a plied in a very thin coating and positively held in a rigid and durable manner.

With this object in view. the invention consists in the use of a fabric or other foundation material, as a suitable felting, which is preferably rendered waterproof by any approved means as by the coating thereof with tar, so that there will be no swelling or warping of the base by reason of the dampness of the applied coat of plastic material, and whereby any looseness of, or hollow spaces in, the plaster coat is avoided.

The preferably felt fabric may be also suitably treated with a fire proofing medium, which treatment may also serve to impart greater rigidity to the structure.

I preferably construct the fabric with spaced perforations through the same in order to provide keys for holding the plaster coating and anchoring it at intervals to the said key base.

The wire structure is preferably placed on each face of the foundation so that the strands thereof will cross each other at the said perforations at which points the wires on one face of the foundation will be soldered or welded to the wires on the other face, which operation I herein call soldering, the said fused joints also serving to reinforce the structure and to afford additional plaster holding means.

By reason of the oppositely disposed strands being drawn toward each other for soldering the same together at the said perforations,the portions of the key base adjacent to the perforations will be thinner than at the other parts thereof.

By the use of my-key base waste of plaster is avoided and a permanent and reliable holding means therefor is secured.

With these and other objects and advantages in view, the invention comprises the construction, arrangement and operation of the several parts which are herein set forth. and also illustrated in the drawings accompanying and forming a part of this specification, and in which:

Figure 1 represents a sectional view of a structure in which the invention is embodied;

ig. 2 is a similar view of a structure in whic the arrangement of some of the wires is changed;

Fig. 3 is a plan view of one of the blocks or sections formed by a spaced group of wifries mounted on an interior fabric base; an

Fig. 4 illustrates one of the soldered joints.

Referring to the drawings, in which a simple form of this invention is shown, the numeral 1 denotes the base or foundation sheet of flexible fabric, as felt, preferably having a coating of tar 17 on which fabric is mounted at intervals groups of wires comprising a series of preferably parallel strands 5 positioned along one face of the face 1 and another series of strands 11 located at the other face of the base and running preferably parallel and at an angle to the wires 5. Said base or foundation 1 and said groups of wires constitute blocks or sections 20. Between the various spaced blocks or sections 20 is an extension and connecting portion of the foundation 1 thereof which I designate as 10. Those parts of the base forming a part of the blocks 20 are preferably made with spaced perforations 3 at which perforations the wires 5 and 11 cross each other and are soldered together as at 16, whereby the blocks 20 are thinner at the perforations 3 than at other parts of the The said soldered wire joints and erforations constitute means for sup- By reason of the allel relation and crossing the wires 11 on the other face of the fabric. Fastening means, as staples 8, may be used to attach the structure to a support, as 7.

I wish it to be understood that I do not desire to be limited to the particular use or the exact details of construction shown and described, for obvious modifications will occur to persons skilled'in this art.

What I claim as my invention is 1. In a device of the class described, a base comprising a sheet of felt having a group of spaced wires disposed in parallel relation on one face thereof and a second group of spaced parallel wires on the opposite face of said sheet, but running in a different direction from those of the first named group, there being spaced perforations in said sheet at points coinciding with the crossing of the wires of the two groups. and solder uniting the. crossing wires at said perforations.

2. In a device of the class described, a base comprising a foundation sheet having a set of spaced wires disposed in parallel relation on one face thereof and another set of spaced parallel wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet at points coinciding with the crossing of the wires of the sald two sets, and fused joints uniting the crossing wires at said perforations.

3. In a device of the class described, a base comprising a foundation sheet having a set of spaced wires disposed in parallel relation on one face thereof and another set of spaced parallel wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet atpoints coinciding with the crossing of the wires of.

the said two sets, and fused joints uniting the crossing wires at said perforations, in combination with additional supplemental wires attached to the said structure and adapted to engage a plaster coat.

4. In a device of the class described, a base comprising a foundation sheet having a set of spaced wires disposed in parallel relation on one face thereof and another set of spaced parallel wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet at at and with the perforations as to constitute means for supporting plaster keys.

5. In a device of the class described. a base comprising a foundation sheet having a set of spaced wires on one face thereof and anotherset of spaced wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet at points coinciding with the crossing of the wires of the said two sets, and fused joints uniting the crossing wires at said perforations.

6. In a device of the class described, a base comprising a foundation sheet having a set of spaced wires onone face thereof and another set of spaced Wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet at points coinciding with the crossing of the wires of the said two sets, and fused joints uniting the crossing wires at said perforations, in combination with additional supplemental wires attached to the said structure and adapted to engage a plaster coat.

7 In a device of the class described, a base comprising a foundation sheet having a set of spaced wires on one face thereof and another set of spaced wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet at points coinciding with the crossing of the wires of the said two sets, and solder uniting the crossin wires at said perforations, the said Solder )OllltS being so arranged at and with the perforations as to constitute means for supporting plaster keys.

8. In a device of the class described, a base comprising a tarred sheet of felt having a set of spaced wires on one face thereof and another set of spaced wires on the opposite face of said sheet, but running in a different direction from those first named, there being spaced perforations in said sheet at points coinciding with the crossing of the wires of the said two sets, and fused joints uniting the crossing of the wires at said perforations.

In testimony of the foregoing description I do hereby sign the same this 4th day of October, 1917.
